NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 564,750, dated July 28,1896.

Application filed January 20, 1896. Serial No. 576,206. (No model.)

T to whom it may concern.-

Be it known that I, JAMES C. HOLLOWAY, a citizen of the United States,residing in the city and county of San Francisco, State of California,have invented certain new and useful Improvements in Nut-Locks and I dohereby declare the following to be a full, clear, and exact descriptionof the same.

My invention relates to a nut-lock; and it consists of the parts and theconstructions and combinations of parts which I shall hereinafter fullydescribe and claim.

In the accompanying drawing the figure represents my invention asapplied to railway fish-plates.

In said drawing, A indicates a plate of thin metal having an opening oropenings made through it for the passage of a bolt orbolts and havingprojecting wings B cut from within and out of the body of the plate andcontained within the outer wall or edge thereof. These wings aredesigned to be bent or turned outwardly in such a manner that they maybe made to lock or secure the nut.

In the drawing the invention is shown as applied to the nuts of railwayfish-plates, although it is not limited to this particular use. Thefish-plate is shown as having two openings, one ,near each end, at sucha distance apart as to receive the two bolts which are used, said boltspassing through said holes and having the plate A fitted over them. Whenthe parts are thus assembled, the nuts are screwed down upon thethreaded ends of the bolts until they are sufficiently tight against theplate, when the projecting wings B are bent or turned outwardly againsttwo of the sides or faces of the nuts. As the nuts must be frequentlytightened I have formed supplemental lugs or spurs 6 upon the edges ofthe wings and formed integral with the latter, and cut from within andout of the hand.

body of the plate and contained within the outer edge thereof, and theselugs are designed to be turned at right angles with the wings, so thatthey may be made to engage the two remaining sides or faces of the nutswhen the wings have been turned up but a little way. The plate A, whichis preferably of mild or malleable steel or iron, can be bent severaltimes without breaking. WVhen the wings and lugs are bent to engage thenuts, as described, the latter will be securely held after they havebeen turned to the proper point.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A nut-lock consisting of a sheet of metal having wings provided withintegral supplemental lugs on opposite sides, said wings and lugs beingcut from within and out of the body of the blank and contained withinthe outer wall or edge thereof, said wings adapted to be bent to engagetwo of the sides of the nut and said lugs adapted to be bent at right.ngles to the wings and to engage the two remaining sides of said nut.

2. In a nut-lock, a plate perforated to receive the bolt, and having awing on each side of the bolt-hole, with integral supplemental lugs,said wings and lugs being cut from within and out of the body of theplate,

and contained within the outer wall or edge thereof, said wings adaptedto be bent to engage the side walls of the nut and said lugs adapted tobe bent horizontally inward, toward each other, and to engage the topand bottom walls of the nut.

In witness whereof I have hereunto set my JAMES C. HOLLOWAY. WVitnesses:
